It probably happened because the combination of two factors:
1. hotlink.cc has reduced the max connection limit per IP.
2. We have a bad handling for disconnecting chunks.
The only "solution" would be for us to hardcode another limit into our hotlink.cc plugin.
I'd rather have a premium account for testing before I do this.
If you want you can provide your account via
support@jdownloader.org.
If you only get good speed with a lot of connections you should consider either trying multiple simultaneous downloads with less chunks for each and/or also contact the hotlink.cc support and ask them to revert their changes/allow more connections or improve their speeds.
